Hi Sir, My brother is having a major chest infection according to doctors and he is deaf and dumb according to MRI and X-ray it shows that 70% chances of TB. But the TB injection test is negative. There is no mark and swelling anywhere. Still doctor has started the TB treatment just for one month trail. His urine is red in color and having itching on legs. Weight is reducing. Also having mild fever. What best we can do please suggest. Is it right to start TB treatment and how long it will take to cure the infection.
